CONDENSER FOR STILLS.

Application filed March 5, 1925.

This invention relates to improvements in Water stills and more particularly to a novel condenser for such a still.

One of the objects ot the present invention is to provide a condenser so constructed that the cooling water will be supplied to the condenser at the most advantageous point to effect rapid and thorough condensation of the water vapors delivered troni the generator with which the condenser is associated.

Another object ot" the invention is to provide a condenser so constructed that obnoxV ious volatile impuritiesI contained in the water bein(r distilled will be carriedot so that the distilled water will be tree from contamination.

Another object of the invention is to provide a condenser embodying means whereby air may bepartially exhausted from the condensation chambers of the condenser to thereby not only remove obnoxious volatile impurities whici may be contained in the water or water vapors but, at the same time,

expedite and facilitate the vaporization of the water and the condensation of the va )oi-s.

nthe accompanying drawings: y Flgure 1 is a Vertical sectional view through a distilling apparatus constructed in accordance with the present invention.

Figure 2 is a horizontal sectional View taken substantiallyon the line 2-2 of Fig urel, looking in the `direction indicated by the arrows.

. The distilling apparatus embodying the invention comprises, generally speaki e, a generator, indicated in general by the nus meral 1, a receiver, indicated bythe numeral w 2. and a. condenser indicated in general by u 678,450, tiled VDecember 4, 1923, and comprises a surrounding wall or walls indicated Serial No. 13,283.

by the numeral and other walls 6 which are spaced inwardly from the walls 5 and connected therewith by a bottom 7 forming a preheating chamber 8 into which water is introduced by a supply pipe 9 provided at its top with a tunnel 10, the purpose of which will be liifesently explained. A bottom wall l1 is arranged within the bounds ot the walls (i, and defines, in conjunction with the upper portions ot said walls 6, a generating chamber 1Q, the walls (3 having openings 13 therein to provide tor the passage ot' preheated water 'from the preheating chamber S to the generating chamber 12, whereby ti constant shallow level of' water is maintained upon the bottom 11 which is rapidly converted into steam, the apparatus being, ot course, arranged with the open bottom of the generator above a source of heat, as, for example, a cooking range. A plate .la is arranged within the generator l and rests upon the upper edges of the Walls G and is formed with pertorations 15 and 16 located respectively above and comiiiunicat- `ing with the pre-heating .chamber 8 and generating chain er l2, so that the steam gener ated in these chambers, and especially in the chamber 12, may pass upwardly through the open top of the generator.

The receiver 2 comprises a hollow body 17 provided in its upper portion with a receiving pan 18 having a number of short nipples or spouts 19 extending upwardly from its surface and establishing communication between the spaces above and below the pan. A water outlet pipe 20 leads from the lowermost portion of the pan, the pan being inclined from all sides toward its said ortion, Aand `serii'es to carry ott' the distilled water. The body of the receiver is rem0vably disposed upon the open top of the body of the generator and the condenser 3 is, in turn, removably supported upon the top of. the receiver.

The condenser l comprises a hollow body dcincd by surrounding walls 20, and the said body is removably disposed at its lower end to rest upon the o 4)en top of the receiver 2 and is provided a ive its open bottoni with a bottom plate indicated by the numeral 21, this plate being formed with a plurality of openings 22 which, in the present instance, are oic rectangular torni. Condensation chambers, indicated in general by the numeral 23, are fitted and secured in a iuid-tight manner at their lower ends in the openings 22 or may be secured to the plate 21 in position to register at their said ends with the said openings, these ends of the chambers being open. The condensation chambers 23 are of rectangular section and of any desired dimensions and arranged in any desired manner over the area of the plate 2l, `and the said chambers are closed at their upper ends by caps 24 preferably permanently united thereto. The space enclosed by the body 20 of condenser 3 above the bottom 2l and surrounding the condensation chambers 23, constitutes a cooling fluid chamber indicated by the numeral 25, and water or other suitable iluid is introduced into this chamber in regulated quantities by a system of piping which will now be described. The numberal 26 indicates a trunkline made up of pipe sections-i and suitable elbows uniting the same, which sur rounds the lower portion of the condenser body 2O in a plane immediately above the bottom 2l thereof, and a water supply pipe 27, leading from any suitable source of supply, isplaced in communication with the trunk at any suitable point and is providedv with a manually adjustable cut-oit valve 28 whereby the iiow of water` to the trunk may becontrolled. A number of branch pipes 29 are placed in communication with the trunk 26 and lead inwardly therefrom and through the walls 'of the condenser body 2O and at their inner ends, which ends are in communication with the interior of the condenser body or, in other words, with the cooling-fluid chamber 25, are preferably flared as indicated by the numeral 30. Preferably7 the arrangment such that the discharge end of each of the delivery pipes 29 will be positioned between two adjacent condensation chambers 23, except that where such pipes are led through the corners of the body 2O of the condenser, the discharge ends of such pipes may be presented directly toward the corner chambers, as best shown in Figure 2 of the drawings, these particular branch pipes being indicated bythe numeral 29. At this point, it willv be evident that the condensation chambers 23 are in communication, at their lower ends, with the space above the receiver 2 so as to receive ther steam or water vapors rising through the nozzles 19, and it will lilewise be evident that the cooling water or other cooling fluid is supplied to the cooling-fluid chamber 25 substantially at the lower ends of the said condensation chambers 23 and is caused to circulate about the chambers and cool the walls thereof to effect condensation of the steam or water vapors.

The numeral 3l indicates an overflow pipe which leads from the cooling-fluid chamber 25 near the top thereof and to any suitable point- Where the overiiow is to ble delivered, a' manually adjustable cut-olf valve 32 being,r arranged in this pipe so as to regulate the overflow in accordance with the delivery of water to the said chamber. The numeral il?) indicates another overllow pipe which leads from the chan'iber 25 and extends down fardly with its lower end en tering` the funnel l0, a manually operable cut-olf valve 2li-t being interposed in this pipe to control the passage of water therethrough. It will be understood at this point, that by providing the pipe 9155, water may bc delivered from the chamber 25 into the funnel l() and discharged from the funnel through thc pipe to the chamber S.

The exhaustingl unit 4i comprises a closed chamber 35 of dimensions and contour to seat in or upon the upper end of the body 2O of the condenser 3, and short pipes liti extend upwardly from the caps 2l olE the condensation chan'lbers 2?) and establish communication between the upper endsy o'lI the said chambers and the boltom portion of the exhausting` chamber 9,5. lhe numeral 3T indicates a pipe which is placed in connnunication at one end with the chamber 35 and leads to any suitable exhaust pump for exhausting air trom thc said chamber, a cut-oil valve 3S beinginterposed in the pipe 37 whereby the outliow ol? air through the pipe may be controlled.

In the operation of thi apparatus, water reaching the surface of the bottom plate ll of the generator will be immediately converted into steam and the steam will rise through the openings 1G in the plate 'll and through the nipples Ill) in the pen 'le' ol. tbc receiver 2, and enter the condensing chambers 23, where it will be condensed and dripped from these chambers onto the pan and delivered through the pipe 20. Due to the suction created in the exhausting chamber 35, the steam is caused to more thoroughly circulate in the condensinglr chambers L3 and heated air currents will likewise be drawn oit from these chambers, so that the steam is more rapidly cooled and rapidly and etlcctually condensed than would otherwise be the case. Likewise, all olmoxious volatile impurities in the water will bc drawn oil by way of the chamber :l5 and exhaust pipe 37, thereby avoiding contamination of the distilled water.

It will be evident that while the condensation chambers 255 are herein illustrated and described as of rectangular form, they may assume some other form if found desirable, without departing from the spirit of the invention as expressed in the claims.

Having thus described the invention, what I claim is:

l. In distilling' apparatus, a condenser casing' having a body wall and a bottom, the latter provided with openings, a plurality oi upright condensation chambers arranged within the casing 'upon the bottom thereof Within said openings, the said chambers being closed at their tops and open at their bottoms to receive the vapors to be condensed, a trunk pipe, means for supplying a cooling fluid thereto and a plurality of branch pipes leading rom the trunk pipe and into the casin through the body Wall near the bottom o' the casing and having their discharge ends presented in proximity to the lower portions of the condensation chambers.
